| Use advice for data set | When using this LCA dataset, note that it only accounts for the production phase of cement using dry rotary kiln technology and excludes the use and disposal phases. Ensure the inclusion of recycled materials such as fly ash in the analysis as it represents a key element of the ecological efficiency of this process. Data users should account for local recycling practices, and the potential environmental benefits of wastewater reuse. This dataset is representative of a major Chinese cement producer and should be contextualized when comparing with other regions or production technologies. |
| Technical purpose of product or process | The described process produces portland-composite cement using dry rotary kiln technology. It applies specifically to cement production processes where mixed solid wastes are utilized. The cement generated is suited for construction activities, especially where a blend of clinker and supplementary cementitious materials like fly ash is acceptable. The fly ash utilization aligns with sustainable practices by reducing the need for virgin raw materials and minimizing waste. |

| General comment on data set | Over 90% of China's cement clinker was produced by applying dry rotary kiln technology in 2013 (China Cement Association, 2014). Therefore, only cement produced by applying dry rotary kiln technology was analyzed.In this enterprise, the flying ash generated from cement production process is recycled as one alternative material for cement production. Wastewater is also recycled for watering local gardens after primary treatment. |
